Hello,
I'd like to know any info about that motherboard. I've tried HWInfo but it doesn't show model name or manufacturer.
On the motherboard itself there is no markings or symbols of the manufacturer.
The info that is displayed during the booting up is :
U4913 Green 486 & DX4 Main Board INV 1.2 94.4.15
40-0105-428003-00101111-080893-UMC491F-F
Thanks in advance
looks a lot like this one http://www.win3x.org/uh19/motherboard/show/6817
Right to repair is fundamental. You own it, you're allowed to fix it.

Yeah, it looks like mine is some sort of rip off of that one
The POST string suggests a QDI motherboard indeed.
However the chipset is different. It seems we don't have it in UH19 (or maybe not identified yet).
Trying to identify old hardware ? Visit The retro web - Project's thread The Retro Web project - a stason.org/TH99 alternative
I checked all 3VLB boards with UMC491/493 or UMC unidentified: no matches.
I searched for the bios string, I was having high hopes but alas:
80386 BIOS image collection
#20 most definitely has the wrong bios flashed to it.
I forgot one category. The chipset ==NULL category.
Is this your board???

No, there are a couple of differences. The biggest one are supported CPU's
Oh, I can do one better. Pages from the User manual.
(For some boards I have these minimal sets from a website somewhere in Russia, downloaded 20 years ago).
for the UH19 page, that comes from MicroHouse/TH99 and they are known to have errors, misplaced jumpers and sometimes even wrong chipsets.
new page for this QDI U4913 board created:
http://www.win3x.org/uh19/motherboard/show/8299
any more info/bios dump (yes please) will go there.

mmmh, Just noticed, there's a 386 board in the bios section here that has almost the exact same bios string 80386 BIOS image collection
40-0105-428003-00101111-080893-UMC491F-F
vs
40-0102-428003-00101111-080893-UMC491F-F
that's annoying. 😀

Yupp, have also found that one
#20 most definitely has the wrong bios flashed to it.
That is an earlier release of your own bios. It is not made for that board.
Your board is already identified as QDI U4913, aka: QDI V4U4913GRN/AUP1, QDI UL486P3 Green Board
Thanks a l0t
